ABSTRACT:
A cased suspended sub-sea well is secured for abandonment by setting a packer in the casing thereof, the packer having a perforating gun suspended therefrom firing the gun to perforate the casing and then injecting cement into the annulus behind the casing. The well is thus sealed and the casing above the packer can then be cut away
